16 So Jesus answered them, a“My teaching is not mine, but his who sent me. 17 If anyone’s will is to do God’s1 will, he will know whether the teaching is from God or whether I am speaking on my own authority. 18 The one who speaks on his own authority bseeks his own glory; but the one who seeks the glory of him who sent him is true, and in him there is no falsehood.

49 For I have not ispoken on my own authority, but the Father who sent me has himself given me a commandment—jwhat to say and what to speak.
John 14:10
